I’m hoping for some suggestions on the best way to allow a snap access to sockets in /tmp/.X11-unix/
I’m moving an existing node app that uses node-x11 into a snap. From what I can tell, node-x11 looks for /tmp/.X11-unix on the file system vs. using the abstract namespace @/tmp/.X11-unix/ I’ve done some googling and it looks there are a few ways to go about this, but most seem like workarounds. I want to make sure I’m not missing an existing feature within snappy that would make this easy / clean.
Thanks for the info! @ogra Unfortunately (for this project) the x11 interface uses only the abstract X11 sockets vs. the sockets created within the file system. @/tmp/.X11-unix/X[0-9]* vs. /tmp/.X11-unix/X[0-9]*
You can use the layouts feature to make some changes to the mount namespace your application runs in. I’m not sure whether it would let you bind /tmp/.X11-unix back in though.
Connecting to X by TCP/IP is probably possible via the network interface, but on many systems these days the X server is configured to only listen on UNIX domain sockets (with people relying on ssh for remote connection).
You might be able to do more with a new interface, but it isn’t clear it would be accepted into upstream: there are good reasons for only exposing the abstract namespace sockets. And it would probably be easier to patch node-x11: you’d need to ship a copy of it with your snap anyway, so it wouldn’t be that difficult to ship your own branch of the module. It also seems like a change they might be willing to accept upstream, so you wouldn’t necessarily be stuck with the maintenance burden forever.
